Learn More70. I assume that calculating the modulus of a number is a somewhat expensive operation, at least compared to simple arithmetic tests (such as seeing if a number exceeds the length of an array). If this is indeed the case, is it more efficient to replace, for example, the following code: res = array[(i + 1) % len];
Learn MoreConversely, if loss modulus is greater than storage modulus, then the material is predominantly viscous (it will dissipate more energy than it can store, like a flowing liquid). Since any polymeric material will exhibit both storage and loss modulus, they are termed as viscoelastic, and the measurements on the DMA are termed as viscoelastic …
